My name is Seth. I'm a detective.

One day, as I was trying to figure out a math problem, an 8 year old boy came in bawling. He cried, in anguish, "My uncle killed himself!"

I quickly asked, "Are you sure he's dead? He could just be asleep. Old people do that, you know."

He cried, "He's not breathing. I'll show you; he's at his house."

So I said, "Then, let's go."

When we arrived at the house (41 North Irving Street) I asked the boy his name. He said, "Jack."

"Okay, Jack," I said. "Show me to the kitchen. I'll get you a drink and clean my hands to begin analysis of the body."

We entered the kitchen, and I turned on the cold water to fill Jack's cup for hot chocolate. But the cold got hot! I asked Jack what was wrong with the pipes, and he said "My uncle is ... was... a lefty, so the cold is on the left side."

After that fiasco, I went into the living room to look at the body. The man was in a rocking chair with a table on each side. On the right table was a bottle labeled "cyanide"

. I swiftly turned to Jack and said, " Your uncle was killed and there is one reason I believe that.

Do you see it?"

Answer: The cyanide bottle was on the right table. If the old man was a lefty, than the bottle would also be on the left table.
